Progress along with technology, people have designed the plug with the overload overheat protection function, for example: Chinese patent 03204261.2 discloses a kind of overload protecting plug, comprise a power line, one plug and an overload protective device, wherein power line comprises a live wire and a zero line, and plug comprises a live wire end pin and a zero line pin, and the zero line of this zero line side pin and this power line is electrically connected; And this overload protective device comprises a live wire contact site and a pin contact site, and the live wire of this live wire contact site and this power line is electrically connected, and the live wire end pin electrical contact of this pin contact site and this plug becomes the normality conducting; Overload protecting plug can bimetal leaf the flexural deformation characteristic, or the resistance value of semistor increase and decrease characteristic can not damaged because of super-high-current power line and socket, or makes the electrical appliance can be not impaired because of the generation of erratic current.
Yet; above-mentioned plug with the overload overheat protection function lacks warning function in actual applications; when overheat protector disconnecting plug circuit; the user does not often know owing to appliance power excessive or overload or the bad problem that causes of plug itself, thereby can not in time reduce the loading level of electrical equipment or get rid of targetedly unusual.Moreover, because the overload Overtemp. protector is generally the bimetal leaf temperature protector, have auto-reset function, when temperature is high, bimetal leaf temperature protector automatic cut-off power, after temperature reduced, the bimetal leaf temperature protector recovered again the conducting of power supply automatically; So; above-mentioned with the overload overheat protection function plug in actual application; owing to do not reach alarm; even appliance circuit is under the fault condition; plug also can make plug switch between cut-out circuit and connection circuit two states incessantly because of the auto-reset function of overload Overtemp. protector; so not only damage easily electric equipment, and can be because the overload Overtemp. protector generates electromagnetic waves reset the time and spark causes larger peril to occur.
The utility model content
The technical problems to be solved in the utility model is for above-mentioned deficiency of the prior art; a kind of overload overtemperature prote plug with warning function is provided; this plug can in time give the alarm when the overload Overtemp. protector cuts off circuit, makes the user know unusually at once, and in time eliminates unusual.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of overload overtemperature prote plug with warning function, comprise power pin, overload Overtemp. protector and load power source line, and described power pin comprises live wire pin and zero line pin; Described live wire pin is behind described overload Overtemp. protector, with the live wire electric connection of load power source line; The zero line of described zero line pin and described load power source line is electrically connected; Also comprise warning circuit, this warning circuit is in parallel with the overload Overtemp. protector.
As to further elaboration of the present utility model:
Described warning circuit comprises dropping resistor, rectifier diode, alarm and filter capacitor, and described dropping resistor, rectifier diode and alarm are in series, and described filter capacitor and alarm are in parallel.
Further, described rectifier diode comprises the first rectifier diode and the second rectifier diode, and the first rectifier diode, alarm, the second rectifier diode are sequentially connected.Described alarm is LED lamp or buzzer.The resistance of described dropping resistor is 200 K Ω～400K Ω, is preferably 300K Ω, and the appearance value of described filter capacitor is 50 μ F～150 μ F, is preferably 100 μ F.
Further, described power pin also comprises earth pin, and described load power source line also comprises ground wire, and the ground wire of described earth pin and load power source line is electrically connected.
The beneficial effects of the utility model are: warning circuit of the present utility model is in parallel with the overload Overtemp. protector, when the plug temperature is low, because the impedance of warning circuit is much larger than the impedance of overload Overtemp. protector, therefore, only from overload Overtemp. protector process, warning circuit is in the non operating state that no current passes through to electric current; And when plug overload or excess Temperature, the overload Overtemp. protector cuts off circuit, and a small amount of electric current passes through from warning circuit; warning circuit is conducting and giving the alarm; therefore, the user can know unusually at once, and in time eliminates the abnormal problem of electrical equipment or plug itself.
